The growth forecast for India is 0.5 percentage points less than IMF's previous two forecasts in April and July.

The latest IMF report puts China slightly ahead of India in terms of growth rate for the year 2017.

Washington: The International Monetary Fund (IMF) on Tuesday lowered India's growth projection to 6.7 per cent in 2017, 0.5 percentage points less than its previous two forecasts in April and July, attributing it to demonetisation and introduction of the GST. It also lowered the country's growth for 2018 to 7.4 per cent, 0.3 percentage points less than its previous two projections in July and April.

India's growth rate in 2016 was 7.1 per cent, which saw an upward revision of 0.3 percentage points from its April report.

"In India, growth momentum slowed, reflecting the lingering impact of the authorities' currency exchange initiative as well as uncertainty related to the mid-year introduction of the country-wide Goods and Services Tax," the IMF said in its latest World Economic Outlook report.

"Strong government spending and data revisions in India led to an upward revision of 2016 growth to 7.1 per cent (6.8 per cent in April), with upward revisions of about 0.2 percentage points, on average, for 2014 and 2015," it said.

The latest report, released ahead of the annual meetings of the IMF and the World Bank here this week, puts China slightly ahead of India in terms of growth rate for the year 2017.

China is projected to grow at 6.8 per cent in 2017, which is 0.1 percentage more than IMF's two previous projections in April and July.

However, India is likely to regain the tag of the fastest growing emerging economies of the world in 2018, with China projected to grow at 6.5 per cent in 2018, it said.

The GST, which promises the unification of India's vast domestic market, is among several key structural reforms under implementation that are expected to help push growth aboveeight per cent in the medium term, the report said.

"In India, simplifying and easing labour market regulations and land acquisition procedures are long-standing requirements for improving the business climate," the reportsaid.

Between 1999 and 2008, India on an average grew at a rate of 6.9 per cent, IMF said adding that for the next three years its's growth rates were 8.5 per cent in 2009, 10.3 in 2010 and 6.6 per cent in 2011.

In the years 2012, 2013 and 2014 it grew at a rate of 5.5 percentage points, 6.4 per cent and 7.5 per cent respectively.
